I do the same thing. If there's a story arc I like I'll rewatch it in my spare time (as opposed to watching...say...filler episodes).

I've rewatched and reread the first story arc about 6 times; and I've seen episodes 48, 49, and 50 too many times to count (that's Gaara and Lee's fight during the prelims btw).

That's still impressive that you remembered that mouth scene Assertn.
